Sunday Ticket on mobile device?

Has anyone tried the NFL Sunday Ticket who doesn't have direct tv? Think it is like $139 for streaming to PC, but not sure how good the feeds and speed are?

 

I use it on my smartphone on the way to church when it's a late game. That way when I get home I don't have as much to catch up on. It is sorta real spotty on the connection though. I just let my wife drive and I watch it going down the road. I have it on my consoles also but when I'm home I just watch it on tv. I've never tried it on my laptop. I'm gonna be on vacation during one of the games and will probably just have to wait til I get home to watch it. Not finding out who won is gonna be a HUUUUGE pain! I just know I'm gonna accidentally see it.
